Notes on Options:

Twist rate mostly affects what types of bullets you can use and your level of Purism:

- 1:14 is what ArmaLite started with in the late 50's and were used for the first 601's. Replaced by 1:12 in about 1962.

- 1:12 what was issued in all AR15 variants from 1962-1984 (Marines) and 1987 by the US Army. Use only 55gr and some 62gr bullets.

- 1:7 can shoot anything you can buy, including 77gr heavies (mk262) and tracers. It is the current NATO Standard twist rate.
